Bully Dog Heavy Duty WatchDog (HDWD) Testimonials

"We have been very impressed with the Heavy Duty Watchdog that we purchased from J&S. We have a 2014 Freightliner with a DD15 engine. Our main reason for purchasing was because we are in and out of Ontario and Quebec every week. It takes us about 30 seconds to set our speed limiter going into Canada and 30 seconds to set it coming out. Purchasing the HDWD has been one of the best deals that we have made in a very long time. We love having the ability to set the speed limiter ourselves. What a time saver as well as money saver the Heavy Duty WatchDog has been for us in the two months that we have had it so far."
